The Massive Attack Squared is a traditional carbon fibre tandem road frame for all round performance with exceptional stiffness-to-weight and ride feel. Hand built tube to tube construction guarantees quality and lifetime durability with infinite scope for customisation.

The headset and cable routing options are all neatly hidden and internal for a clean, modern aesthetic.

Each frame is built from scratch with bespoke custom geometry for both pilot and stoker.


Each WyndyMilla frame comes with a full bike fit and a simple but fully custom paint design included in the price. If you want to go further though, the sky really is the limit. Either way, work with our designers to describe your dream combination of colours and finishes then add your own personal touches like names, motifs, slogans etc. Once you agree the final digital artwork, WM Paintworks will work their magic and bring your frame to life.
